A year prior to the first scene, Stan Laurel married Oliver Hardy's sister (played by Oliver), and Oliver married Stan's sister (played by Stan) in a double wedding. They all live together and Stan and Ollie work in the same office. After some gags involving telephones, the wives are seen making preparations for a surprise party to celebrate their first anniversary during which a cake lands on Mrs. Laurel's head, causing her to bear an uncanny resemblance to a portrait of Elizabeth I on the dining room wall. Stan and Ollie then arrive but the couples cannot help but squabble throughout the party. In the final scenes a delivery boy (played by Charlie Hall (actor)) arrives with another cake which is thrown in Mrs. Laurel's face by an acrimonious Mrs. Hardy.
